Seemingly a cheerful and normal kid, Lock is a ruthless general in Queen Dyspear's army. Nearly always calm, Lock is sassy, sadistic, childish and gets bored easily when there's no chaos or fighting, so he usually has fun by upstanding and embarrassing his fellow musketeers, making everything a game, and cheating when necessary. Lock gets serious when he's not having any fun. Lock uses "'kay?" in most statements that he says (usually at the start or end). And he hates those Princess Precures.
